The Obsidian Blade X was the most powerful upgrade of the Obsidian Blade, stronger than the Obsidian Blade V3. It could be bought in Challenge Mode for 100,000 bolts. It replaces the Obsidian Blade V3. Through in-game unlockable cheat, "Super Morphing Freeze Wrench", the wrench could Freeze enemies and Morph them into farm animals when defeated. Its appearance is almost identical to the OmniWrench 12000, but set on fire.
